    The compression ratio describes how efficiently a crafted item can be transported, compared to its inputs.. There are two ratios to consider: the stack compression ratio and the belt compression ratio.. The stack compression ratio is how many stacks of input it takes to create one stack of output. For example, Iron Plate has a stack ratio of 2:1 because it takes 200 Iron
